I also choose to avoid the first fifteen minutes. I guess it depends on what vehicle you trade and how you define the open. I only trade the ES and while I sit out the first fifteen minutes, I find the next 45 minutes i.e. 9:45 - 10:30 EST to be the best trading time of the day, bar none.Quote from coolweb:
theres many reasons why to avoid the first 15 minutes,
people who want to trade the first 15 minutes fine.
Whether that categorizes me as avoiding the open or trading it - I don't know nor care.
